Ronan Hale is the first switch since Eunan O'Kane, or since Martin O'Neill took over, as far as I'm aware. I'm under the impression O'Neill wouldn't be overly forward in terms of trying to recruit northern players for fear he'd damage relations with his playing-days association.
It's mentioned there that Ronan Hale is the grandson of Danny Hale, formerly of Crusaders. I'd asked Jimmy McGeough Sr. a while back had he known of any other players who'd liked to have played for the FAI around the time he was trying to get approval for it back in the late '60s and he actually mentioned Danny Hale along with Danny Trainor. I see Hale had
3 "amateur caps" for the IFA in the early '60s; not sure what the official status of those were exactly.
